Final rule. FAA Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes We are adopting a new airworthiness directive (AD) for certain Boeing Model 737- 300, -400, and -500 series airplanes. This AD requires an inspection to determine the manufacturer and manufacture date of the oxygen masks in the passenger service unit and the lavatory and attendant box assemblies, corrective action if necessary, and other specified action. This AD results from a report that several passenger masks with broken in- line flow indicators were found following a mask deployment. We are issuing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.

Final rule. FAA Airworthiness Directives; Airbus Model A330 and A340 Airplanes SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Two A330 operators have reported that the guide shaft of the Refuel Isolation Valve has been broken away from the main casting and entered the fuel tank. The Supplier Investigation evidenced that water builds-up in the cavity of the Refuel Isolation Valve and freezes during flight. When refuel pressure is applied to the piston, the ice restricts the piston travel on one side leading to an asymmetric movement of the piston resulting in breakage of the guide shaft. A non-bonded metallic object within the fuel tank can result [in] a potential ignition source, which in combination with a lightning strike constitutes an unsafe condition.

Emergency AD for popular fuel-injection systems Pilots who fly behind engines with certain Precision Airmotive RSA-5 and RSA-10 series fuel injection servos must have their aircraft inspected and repaired by a mechanic before their next flight under an emergency airworthiness directive (AD) issued by the FAA.The March 12 AD affects all newer-model single-engine Cessnas and some Pipers, as well as overhauled and new replacement engines, and engines that have had fuel injection gaskets replaced. The AD comes stems from the possibility that a loose brass regulator plug could cause significant or complete engine power loss and follows a service bulletin from Precision Airmotive. In one case, an aircraft engine lost power and misfired during flight, resulting in an off-airport landing and significant damage to the airplane.In addition to the initial inspection and repair, the AD requires repetitive inspections every 50 hours or at every engine oil change, whichever comes first.

Final Rule; Delay of compliance dates. Extended Operations (ETOPS) of Multi Engine Airplanes The Federal Aviation Administration (FAA) is delaying the compliance date for certain sections of a final rule, published January 16, 2007, that established regulations governing the design, operation, and maintenance of certain airplanes operated on flights that fly over 180 minutes from an adequate airport. The extension of the compliance date is necessary to give operators additional time to gain a comprehensive understanding of Extended Operations (ETOPS) requirements, develop training and procedures, and implement safety measures established in the final rule. In addition, the regulatory text for certain sections is amended to reflect this delay of compliance dates.

Final Rule: FAA Airworthiness Directives; McDonnell Douglas Model DC-10-10 and DC-10-10F Airplanes, Model DC-10-15 Airplanes, Model DC-10-30 and DC- 10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, Model MD-10-10F and MD-10-30F Airplanes, and Model MD-11 and MD-11F Airplanes. We are adopting a new airworthiness directive (AD) for all McDonnell Douglas airplane models identified above. This AD requires revising the FAA-approved maintenance program, or the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness, as applicable, to incorporate new AWLs for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. For certain airplanes, this AD also requires the initial accomplishment of a certain repetitive AWL inspection to phase in that inspection, and repair if necessary. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

FAA Emergency Airworthiness Directive. This emergency airworthiness directive (AD) 2008-06-52 is sent to all owners and operators of Thielert Aircraft Engines GmbH (TAE) Model TAE 125-02-99 engines. This emergency AD results from reports of in-flight engine shutdown incidents on aircraft equipped with a TAE 125-02-99 engine. This was found to be the result of a cracked high-pressure fuel line between the high-pressure pump and fuel rail. These cracks were caused by excessive vibration of the fuel line. This condition, if not corrected, could result in an in-flight engine shutdown or engine fire.
